SPECIFICATION formingpart of Letters Patent No. 530,589, dated December 11,1894.` i

Application filed January 22, 1894. Serial No.`4`97,625 (No model.)

To a/ZZ whom it may concern:

Be it known that I, PETER O. JOHNSON, a subject of the King of Swedenand Norway, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Mangles, of which the following is a specification.

enlarged end elevation of the cylinders,a portion of their supports being in vertical section. n Fig. 5, is a face representation of the support for the perforated pipes, and vapor generator connected therewith.

To the underside of the table 1, are secured bearings 2 and 3, the former provided with an annular recess 4, in one face, and with a central perforation 5, within which recess is located the reduced end 6, of the lower cylinder 7, in such a manner as to t revolve freely therein, and to the other end of the cylinder is secured abeveled toothed wheel 8, provided with a trunnion 9, which is located in the bearing 3, and to the end of which is connected a crank 10, by means of which it is rotated. From the upper face of the table rise posts 11, having their upper ends screw threaded.

A bearing 12, similar in construction to the' bearing 2, above described supports one end of the upper roller 13, and is provided with horizontal arms 14, which are perforated and receive the vertical posts 1l. Spiral springs 15, are placed around the posts above the A cured thereto and provided Withal trunnion 18,

which is seated in a support 19, which is also provided with horizontal arms 20, which are Fig. 3, is a transverse section on dotted line b, Fig. 1. Fig. 4, is an` perforatedandreceive thevertical posts rising' from that end of the table which have spiral Vsprings 2l, surrounding their upper portion and thumb "nuts 22, having a screw thread connection with the posts form the means for regulating' the tension of the springs.

The bearing 3,isprovided with an upward extension 23, which has a horizontal perforation at its upper end 24, and within which is seated a toothed pinion 25, meshing with the teeth of the beveled gear wheel 8, and from the under face of the bearing 19, depends a projection 26, provided with a vertical recess 27, within which is located a shaft 28, capable of a rotary movement, but held from endwise movement by the pin V29. Upon this shaftis rigidly lixed a toothed pinion 30,which meshes with` the teeth of the beveled gear wheel 17, secured to the end of the upper roller. This shaft 28, has a feather connection with the toothed pinion 25,which meshes with Y the teeth of the beveled toothed wheel secured to the end of the lower roller. The goodsto be mangled are passed between the rollers and made yielding to accommodate the thickness of the goods being mangled, and the feather connection between the shaft 28, and the toothed pinion 25, permits of such adjustment. p

A rotary motion is imparted to the lower roller by means of the handle 10, which motion is transmitted to the upper roller through the gear connection above described.

To one edge of the table is secured a bearing shown at Fig. 5, consisting of arms 31, which support two perforated bearings 32,and 33, and within these bearings` are supported tubes 34,which are extended within the rollers, and have their upper faces provided with perforations. These tubes are connected to a vertical tube 35, which has a connection with avapor generator. A gasoline tank 37, has a connection with the vapor generator bythe tubing 38, and each of the tubes 34, is pro- V the upper roller being held by spring force is u. r

vided with a valve 39. The gasoline being vaporized by the generator passes through the tubes and escapes through thefperforations where itis ignited, and the tubes being located within the rollers, the rollers will be'heated to the proper degree which may be regulated IOO l by the valves 39, .and the valverof the vapor vlocated between thebearings and thumb nuts,

generator.

I claim as my invention- In a mangle the combination of a' suitable supporting table, a roller having its axis located below the table and a roller located above the table, one end of each roller held in tubular bearings, the other end of each roller having a gear wheel secured thereto, the .p

bearings for the upper roller encircling'vertical guides having their upper ends screw' threaded receiving thumb nuts, 4and springs a pinion for the gear Wheel of the lower roller held within a suitable bearing, a pinion for the gear wheel of the upper roller, ashaft connectsing the pinions, a crank having a connection with the-lower roller, and vapor burners located within the rollers.
